A vulnerability in the application CLI of Cisco Prime Infrastructure and Cisco Evolved Programmable Network Manager could allow an authenticated, local attacker to gain escalated privileges. This vulnerability is due to improper processing of command line arguments to application scripts. An attacker could exploit this vulnerability by issuing a command on the CLI with malicious options. A successful exploit could allow the attacker to gain the escalated privileges of the root user on the underlying operating system.

Weakness

The product does not restrict or incorrectly restricts access to a resource from an unauthorized actor.

Extended Description

Access control involves the use of several protection mechanisms such as:

When any mechanism is not applied or otherwise fails, attackers can compromise the security of the product by gaining privileges, reading sensitive information, executing commands, evading detection, etc. There are two distinct behaviors that can introduce access control weaknesses:

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
